We investigated the performance of a 15.3 L capacity anaerobic baffled reactor （ABR） toward the treatment of low-strength domestic wastewater. The start- up period of the ABR was finished within approximately 130 days at a temperature below 25~C. The average CODcr in the effluent was 165 mg.L 1 and the corresponding CODcr removal efficiency of the ABR was 52.3%. During the third stage （from day 130 to day 233） of ABR operation, the average CODcr in the effluent reached 71 mg· L^-1, which meets the secondary discharge requirement of the Integrated Wastewater Discharge Standard （GB 18918-2002, China）. Moreover, partial microbial separa- tion was observed along the five ABR compartments through scanning electron microscopic images. The geometric mean diameter of bioparticles in the five compartments increased from 0.050 mm to 0.111, 0.107, 0.104, 0.110, and 0.103 mm during the start-up stage. After operation for 179days, the further increased to 0.376, corresponding diameters 0.225, 0.253, 0.239, and 0.288mm, respectively. The fractal dimensions of the bioparticles indicated that these particles have smoother surfaces and more compact structures during ABR operation. Morphological analysis of the bioparticle sections demonstrated that the bioparticles have a pore volume of 30%-55%. The highest porosity was observed for the bioparticles in the second ABR compartment, whereas the lowest fractal dimension ofbioparticle section was observed in the fifth compartment.

The ever-increasing concentration of CO in the atmosphere has raised great concerns over carboncapture *** increase the CO adsorption capacity, MIL-101（Cr）has been doped with2-aminoterephthalic acid ligand and then modified with polyethylenimine（PEI）. The properties of the product were characterized by X-ray diffraction（XRD）, Scanning electronmicroscopy（SEM）,Transmission electron microscopy（TEM）, Infrared spectroscopy（IR）and Thermal gravimetric（TG）.The sorbent performance was estimated through acombination of CO adsorption capacity, CO/N selectivityand regeneration performance. The results showed that compared to unmodified MIL-101（Cr）,the CO uptake capacity was increased from 1.75 to2.79mmol/g（a 60% increase） at normal temperature and pressure. Also, the selectivity of CO/N was remarkably enhanced from 12 to 39,increased by 225%. The CO adsorption enthalpy reached 239 k J/mol. Moreover, these sorbents can be completely regenerated under vacuum of 0.001 Pa at 80 ℃. Thus, this approach offers new insights into designing of more competitive materials for CO capture.

Nitrogen removal characteristics of heterotrophic nitrification-aerobic denitrification by Alcaligenes faecalis C16

引用

Chinese Journal of Chemical Engineering 2015年第5期23卷 827-834页

作者： Yuxiang Liu Yao Wang Yi Li Hua An Yongkang Lv College of Environmental Science and Engineering Taiyuan University of Technology National Major Science and Technology Program Management Office for Water Pollution Control and Treatment Shanxi Key Lab of Coal Science and Technology Taiyuan University of Technology

Alcaligenes faecalis C16 was found to have the ability to heterotrophically nitrify and aerobically denitrify. In order to further understand its nitrogen removal ability and mechanism, the growth and ammonium removal response were investigated at different C/N ratios and ammonium concentrations in the medium with citrate and acetate as carbon source separately. Furthermore, experiments of nitrogen sources, production of nitrogen gas and enzyme assay were conducted. Results show that the bacterium converts NH+4-N and produces NH2 OH during the growing phase and nitrite accumulation is its distinct metabolic feature. A. faecalis C16 is able to tolerate not only high ammonium concentration but also high C/N ratio, and the ammonium tolerance is associated with carbon source and C/N ratio. The nitrogen balance under different conditions shows that approximately28%–45% of the initial ammonium is assimilated into the cells, 44%–60% is denitrified and several percent is converted to nitrification products. A. faecalis C16 cannot utilize hydroxylamine, nitrite or nitrate as the sole nitrogen source for growth. However, nitrate can be used when ammonium is simultaneously present in the medium. A possible pathway for nitrogen removal by C16 is suggested. The preliminary enzyme assay provides more evidence for this nitrogen removal pathway.

The Microcystis sample was selected from natural bloom water,then the algicidal effects of the bacterial strain fluid of the two algicidal bacteria,supernatant and bacterial liquid were studied. Moreover,the changes of microalgae colony and morphology in the process of algae-lysing were observed using neutral red staining and scanning electron microscope. It showed that AA06 bacteria had certain algicidal effect while AA10 bacteria had no effect. All the supernatants of the two bacterial strains had obvious algicidal effects,and the algicidal effects between the bacterial liquid and supernatant had no significant differences( P < 0. 05). The effects of algae-lysing mainly owed to the chemical substances secreted by algicidal bacteria. During the algae-lysing process,the algae colony did not disperse into individual cells. The segments of the dead cells still aggregated together.

Occurrence of bisphenol A in surface and drinking waters and its physicochemical removal technologies

Bisphenol A （BPA）, an endocrine disrupting compound, has caused wide public concerns due to its wide occurrence in environment and harmful effects. BPA has been detected in many surface waters and drinking water with the maximum concentrations up to tens of μg · L-1. The physicochemical technology options in eliminating BPA can be divided into four categories： oxidation, advanced oxidation, adsorption and membrane filtration. Each removal option has its own limitation and merits in removing BPA. Oxidation and advanced oxidation generally can remove BPA efficiently while they also have some drawbacks, such as high cost, the generation of a variety of transformation products that are even more toxic than the parent compound and difficult to be mineralized. Only few advanced oxidation methods have been reported to be able to mineralize BPA completely. Therefore, it is important not only to identify the major initial transformation products but also to assess their estrogenic activity relative to the parent compounds when oxidation methods are employed to remove BPA. Without formation of harmful by-products, physical separation methods such as activated carbon adsorption and membrane processes are able to remove BPA in water effluents and thus have potential as BPA removal technologies. However, the necessary regeneration of activated carbon and the low BPA removal efficiency when the membrane became saturated may limit the application of activated carbon adsorption and membrane processes for BPA removal. Hybrid processes, e.g. combining adsorption and biologic process or combining membrane and oxidation process, which can achieve simultaneous physical separation anddegradation of BPA, will be highly preferred in future.

Ru(III) catalyzed permanganate oxidation of aniline at environmentally relevant pH

Ltd. Waters Co. State Key Laboratory of Pollution Control and Resources Reuse College of Environmental Science and Engineering Tongji University

Ru（Ⅲ） was employed as catalyst for aniline oxidation by permanganate at environmentally relevant pH for the first time. Ru（Ⅲ） could significantly improve the oxidation rate of aniline by 5-24 times with its concentration increasing from 2.5 to 15 μmol/L. The reaction of Ru（Ⅲ） catalyzed permanganate oxidation of aniline was first-order with respect to aniline, permanganate and Ru（Ⅲ）, respectively. Thus the oxidation kinetics can be described by a third-order rate law. Aniline degradation by Ru（Ⅲ） catalyzed permanganate oxidation was markedly influenced by pH, and the second-order rate constant （ktapp） decreased from 643.20 to 2.67 （mol/L）^-1 sec^-1 with increasing pH from 4.0 to 9.0, which was possibly due to the decrease of permanganate oxidation potential with increasing pH. In both the uncatalytic and catalytic permanganate oxidation, six byproducts of aniline were identified in UPLC-MS/MS analysis. Ru（Ⅲ）, as an electron shuttle, was oxidized by permanganate to Ru（Ⅵ） and Ru（Ⅶ）, which acted the co-oxidants for decomposition of aniline. Although Ru（Ⅲ） could catalyze permanganate oxidation of aniline effectively, dosing homogeneous Ru（Ⅲ） into water would lead to a second pollution. Therefore, efforts would be made to investigate the catalytic performance of supported Ru（Ⅲ） toward permanganate oxidation in our future study.

Differences in rheological and fractal properties of conditioned and raw sewage sludge

引用

Journal of Environmental Sciences 2013年第6期25卷 1145-1153页

作者： Hui Jin Yili Wang Ting Li Yujing Dong Junqing Li Beijing Key Laboratory for Source Control Technology of Water Pollution Beijing Forestry University

Rheological tests for raw and conditioned activated sludge （AS） or anaerobic digested sludge （ADS） show that power-law relationships can be used to describe the evolution of several rheological parameters, i.e., limiting viscosity （η∞）, yield stress （τy）, cohesion energy of the sludge network （Ec）, and storage modulus （G＇）, with total suspended solid （TSS） content in raw and conditioned sludge. A gel-like structure that behaves similar to weak-link flocs/aggregates was observed in AS and ADS. As derived from the double-logarithmic plots of G＇-TSS content, the mass fractal dimensions of the raw and conditioned AS or ADS flocs/aggregates were 2.70 and 2.53 or 2.85 and 2.79, respectively. The theological tests also indicate that both polymer conditioning and increased TSS content led to improved elastic behavior, cohesion energy, and yield stress of the sludge network, as well as expanded the corresponding linear viscoelastic range. The porosity of AS or ADS flocs/aggregates will be improved by polymer conditioning.

Effects of solution conditions on the physicochemical properties of stratification components of extracellular polymeric substances in anaerobic digested sludge

Journal of Environmental Sciences 2013年第1期25卷 155-162页

作者： Dongqin Yuan Yili Wang College of Environmental Science and Engineering Beijing Key Lab for Source Control Technology of Water PollutionBeijing Forestry University

The composition and effects of solution conditions on the physicochemical properties of the stratification components of extracellular polymeric substances （EPS） in anaerobic digested sludge were determined. The total EPS in anaerobic digested sludge were extracted by the cation exchange resin method. Another EPS extraction method, the ceutrifugation and sonication technique was employed to stratify the EPS into three fractions： slime, loosely bound （LB）-EPS, and tightly bound （TB）-EPS from the outside to the inside of the anaerobic digested sludge. Proteins and polysaccharides were dispersed uniformly across the different EPS fractions, and humic-like substances were mainly partitioned in the slime, with TB-EPS second. Protein was the major constituent of the LB-EPS and TB-EPS, and the corresponding ratios ranged from 54.0% to 65.6%. The hydrophobic part in the EPS chemical components was primarily comprised of protein and DNA, while the hydrophilic part was mainly composed of polysaccharide. In the slime, the hydrophobic values of several EPS chemical components （protein, polysaccharide, humic-like substances and DNA） were all below 50%. The protein/polysaccharide ratio had a significant influence on the Zeta potentials and isoelectric point values of the EPS： the greater the protein/polysaccharide ratio of the EPS was, the greater the Zeta potential and the higher the isoelectric point value were. All Zeta potentials of the EPS showed a decreasing trend with increasing pH. The corresponding isoelectric point values （pH） were 2.8 for total EPS, 2.2 for slime, 2.7 for LB-EPS, and 2.6 for TB-EPS. As the ionic strength increased, the Zeta potentials sharply increased and then gradually became constant without charge reversal. In addition, as the temperature increased （〈 40℃）, the apparent viscosity of the EPS decreased monotonically and then gradually became stable between 40 and 60℃.
